APPARATUS FOR GENERATING GAS.

SPECIFICATIQN forming part of Letters Patent No. 356,2 i7, dated January18, 1857.

Application filed June 2, 1886. Serial No. 203,921. (No model.)

To aZZ whom, it may concern.-

Beit known that I, ALPHRANZO A. HAR- WOOD, of Scottdale, in the countyof Westmoreland and State of Pennsylvania, have invented a new andImproved Apparatus for Generating Gas, of which the following is a full,clear, and exact description.

The object of my invention is to provide a new and improved apparatusfor generating gas by mixing hot air, oil, and superheated steam.

The invention consists in the peculiar construction and arrangement ofparts, as will be hereinafter fully described, and pointed outin theclaims.

Reference is tobe had to the accompanying drawing, forming a part ofthis specification, in which the figure represents a verticalcrosssection of my improvement.

The furnace A, of suitable construction, is provided with the usualfire-place, B, and the boiler G. A retort, D, is situated in thefireplace B, above the gratebarslland is attached at the ends to thehollow shafts F and F, respectively, which shafts have their bearings inthe side walls, A, of the furnace A. The hollow shaft F is provided onthe outside of the furnace A with the pulley G, by means of which theretort is rotated. The stationary pipe H passes through the shafts F andF, and through the retort D, and is provided on the part in the retortwith the curved branch pipes I and the intermediate deflecting andretarding plates or disks, J. The apertures H are formed in theperiphery of the pipe H, near one end of the retort D, and a partition,H", is placed into the pipe H, near the apertures H.

To one outer end of the stationary pipe H is secured ahead, L, into theupper end of which leads the pipe M, coiled in the walls of the furnace,passing through the airspacein the furnace, and connecting with the domeof the boiler 0, so that the steam from the boiler G, passing throughthe pipe M, is superheated when it reaches the head L.

The pipe N enters the head L on the side opposite to that on which thepipe lVI enters said head, and is'connected with the pump 0, whichforces a continuous stream of oil into the pipe N andinto the head L.The pipe 1? is connected with the center of the head L, and

is coiled around the fire-placein the side walls 1 of the furnace A, andit connects at its other end with a fan or air-comprcssor, Q, whichforcesa constant stream of air (which is heated by its passage aroundthe fire-place of the furnace) into the head L.

It will be seen that the superheated steam, the hot air, and the oilpass at the same time into the head L, and are forced into the pipe H,which discharges into the revolving and heated retort D.

The steam, air, and oil are thoronghly'mixed in the revolving retort D,and the generated gas passes through the opening H into the pipe H, andout of the same at its outer end.

The gas generated by this method can be used for various purposes.

I am aware that itis old to generate gas from an admixture of ahydrocarbon, steam, and heated air, and I am also aware that a revolvingretort is old, and I therefore do not claim such inventions. In myapparatus I employ a retort which revolves around a stationary pipeprovided with radial pipes extending to within a short distance of theinner surface of the retort, and with deflecting and retarding plates ordisks between the radial pipes, whereby the steam, air, and oil will bethoroughly mixed and heated. By my construction, also, the mixture ofsteam, air, and oil being delivered into the retort through the radialpipes against the inner surface of the same, it is greatly protectedfrom the heat, and consequently will last much longer.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an apparatus for generating gas, the combination, with a furnace,a retort journaled in the same, and means for revolving the retort, of apipe for conducting steam, air, and oil in the retort, extending throughthe said retort, and provided with radial pipes, and intermediatedeflecting and retarding plates or disks, substantially as herein shownand described.

2. In an apparatus for generating gas, the combination,with a furnace, aretort journaled in the same, and means for revolving the retort, of apipe for conducting steam, air,-and oil into the retort, extendingthrough the said combination of a furnace, a retort journaled retort,and provided with radial pipes, intermediate deflecting and retardingplates or disks, a partition at one end, and apertures between thepartition and the end of the retort, substantially as herein shown anddescribed.

3. In an apparatus for generating gas, the

in the same, means for revolving the retort, a pipe extending throughthe retort and provided with radial pipes,intcrniediate deflecting andretarding plates or disks, apertures near one end of the retort and apartition near the apertures, and pipes for conducting superheatedsteam, hot air, and oil into the pipe, ex-
